Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular is an adjustable wound flushing device for trauma orthopedics. Background Art

[0002] Traumatology is a comprehensive department that mainly studies the anatomy, physiology and sports biomechanics of the musculoskeletal system. This discipline includes a variety of diseases such as traumatic fractures, joint dislocations, ligament injuries, meniscus injuries and spinal injuries. Fractures are common traumatic diseases. Postoperative wound infection and non-healing affect fracture healing and prevent limb function from recovering normally, which is often a very difficult problem for orthopedic surgeons.

[0003] In clinical practice, if there is a lot of exudate at the fracture incision site and the incision has not healed in time for a long time, the clinician should open the patient's wound in time so that the incision can be fully drained. At the same time, gentamicin and saline are used to rinse and wet the infected wound site. The purpose of cleaning is to actively remove surface contaminants, loose debris, detached or softened necrotic microorganisms and / or residues of previous dressings on the wound surface and the surrounding skin.

[0004] The traditional way of cleaning wounds is for nurses to directly use a syringe to flush the wound. Later, with the development of science and technology, a large number of wound flushing devices appeared, most of which are composed of pump components, connecting pipes and flushing nozzles. In actual flushing situations, the cleaning of a single wound is also considered. However, in the actual treatment environment, some patients may have multiple wounds. When the two wounds of the patient are close, the flushing nozzle is generally moved directly to the wound. However, during this movement, impurities from the previous wound may be moved to the next wound. However, if the pump component is turned off and then turned on again, the operation is cumbersome and the repeated startup of the machine will increase its loss. For this reason, it is necessary to propose an adjustable wound flushing device for trauma orthopedics that is convenient for cleaning multiple wounds that are close. Summary of the invention

[0005] In order to solve the problem that flushing is not convenient enough when the patient has multiple nearby wounds, the purpose of the present invention is to provide an adjustable wound flushing device for trauma orthopedics. Through the design of the baffle and the spring and the use of the inertia force of the spring, the flushing channel can be flexibly shielded and the flushing nozzle can be moved to the corresponding position for the corresponding cleaning operation, thereby reducing the loss of repeated switching of the equipment.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an adjustable wound washing device for trauma orthopedics, comprising a liquid storage tank, a wound support portion is provided on the top of the liquid storage tank, a pump assembly is connected to the inside of the liquid storage tank, an output shaft of the pump assembly is connected to an output pipe, and an end of the output pipe away from the pump assembly is connected to a washing nozzle;

[0007] The flushing nozzle includes a fixed body, in which a flushing channel is provided, the flushing channel is connected to the output pipe, a baffle and an auxiliary ring are provided at one end of the fixed body away from the output pipe, the baffle is provided with a through hole corresponding to the position of the flushing channel, the baffle is fixedly connected to a plurality of first springs along its circumference, and the other end of the first spring is fixedly connected to the inner side of the auxiliary ring.

[0008] The principle of the basic solution is: when cleaning the wound of the patient, first place the wound of the patient on the wound support part, the medical staff holds the flushing nozzle and starts the pump assembly at the same time, the flushing liquid will flow to the output pipe under the drive of the pump assembly, and the flushing liquid will be sprayed from the flushing nozzle, and then the flushing nozzle is aimed at the wound of the patient, so that the wound of the patient can be cleaned;

[0009] At the same time, some patients may have multiple wounds, and then after flushing one wound of the patient, the flushing nozzle is moved to a certain position to clean the other wounds. When the two wounds of the patient are close to each other, the flushing nozzle is generally moved directly to the wound. However, during this movement, impurities in the previous wound may be moved to the next wound. However, if the pump assembly is turned off and then turned on again, the operation is cumbersome and the repeated startup of the machine will increase its loss. Therefore, in the present invention, when the medical staff moves the flushing nozzle to the next wound, because the baffle is initially supported and balanced by a plurality of first springs, the baffle on the baffle can The through hole is connected with the flushing channel, so that the flushing liquid can flow out smoothly and flush the wound. When the flushing nozzle is moved, under the action of inertia, part of the first spring will contract and part of the first spring will extend, and at this moment the through hole of the baffle will be misaligned with the position of the flushing channel, and the flushing liquid cannot be output at this time, thereby temporarily closing the flushing nozzle. When the nozzle moves to the next wound, because the flushing nozzle does not perform corresponding movement at this time, the inertia brought by the movement of the first spring disappears, and the first spring is reset, thereby realizing the realignment and connection between the through hole on the baffle and the flushing channel, thereby realizing flushing of the next wound of the patient.

[0010] The beneficial effects of the basic scheme are: 1. Compared with the prior art, the present invention can directly clean multiple wounds of the patient, and when moving to different wounds, there is no need to repeatedly open and close the flushing nozzle, thereby reducing the wear and tear of the flushing equipment.

[0011] 2. By utilizing the inertia force of the spring, the flushing channel can be flexibly opened and closed according to actual needs, thereby facilitating medical staff to perform quick and convenient flushing operations and reducing operational difficulty.

[0012] Furthermore, a cavity is provided at one end of the fixed body away from the baffle, a pulse generator is provided in the cavity, the pulse generator is connected to an actuator, the actuator is located in the cavity, and the pulse generator is electrically connected to a power supply.

[0013] The beneficial effect of the basic scheme is: when flushing, the pulse generator can be turned on, and then the actuator executes the corresponding pulse model emitted by the pulse generator, and then the flushing nozzle can produce a corresponding pulse movement, and the first spring can produce a corresponding telescopic movement under the influence of the movement again, so that the baffle moves to a certain amplitude, so that the through hole and the flushing channel can achieve position change, and then the flushing liquid can be in a large and small form to flush the patient's wound, thereby reducing the problem of high-pressure flushing of the patient's wound and causing patient discomfort.

[0014] Furthermore, the auxiliary ring is composed of a plurality of moving rods forming a square rectangular ring, the moving rods are provided with sliding blocks at one end close to each other, the moving rods cross through the sliding blocks and extend outside the sliding blocks, the sliding blocks are provided with a first protrusion at the bottom, a fixed body is provided with a plurality of first slide grooves corresponding to the positions of the first protrusions at one side close to the sliding blocks, the sliding blocks and the fixed body are slidably matched through the first protrusions and the first slide grooves, and one end of one of the sliding blocks away from the baffle is fixedly connected with a push rod, the push rod passes through the fixed body and extends outside the fixed body;

[0015] A second protrusion is provided at the bottom of the center of the moving rod, and a second sliding groove corresponding to the position of the second protrusion is provided on the fixed body. The moving rod and the fixed body are slidably matched through the second protrusion and the second sliding groove.

[0016] The beneficial effect of the basic scheme is: by pressing the push rod with hand, the sliding block can slide under the action of the push block. When sliding, the first protrusion and the first sliding groove at the bottom of the sliding block can slide and cooperate. At the same time, because the moving rods cross-pass the sliding block and extend outside the sliding block, the moving rods can perform corresponding sliding movements under the movement of the sliding block. When the push rod is pressed, the sliding block moves toward the side of the baffle, and the moving rod also moves toward the side of the baffle. At the same time, because the sliding block and the moving rod form a square as a whole, the other moving rods and the sliding block can move as a whole under the drive of the push rod. When the moving rods move toward the side of the baffle, the elastic path of the first spring can be reduced, otherwise the elastic path of the first spring can be increased, thereby realizing that the through hole at the baffle can flexibly change the connection size with the flushing channel, thereby adjusting the water pressure of the flushing liquid.

[0017] Furthermore, the wound support portion includes a support plate and a hollow support column arranged from top to bottom, a fan blade assembly is arranged in the hollow portion of the support column, the fan blade assembly includes a rotating shaft and a plurality of fan blades fixedly connected to the rotating shaft, and both ends of the rotating shaft are rotatably connected to the inner wall of the support column;

[0018] The output pipe is fixedly connected to the top of the liquid storage tank, and the output pipe passes through the hollow part of the support column and extends out of the hollow part of the support column, and the fan blade is located in the output pipe, one end of the rotating shaft passes through one side of the output pipe and extends into the hollow part of the support column, a sealing ring is provided at the connection between the rotating shaft and the output pipe, and one end of the rotating shaft located in the support column is fixedly connected to a cam;

[0019] A guide rod is fixedly connected to the bottom of the support plate. The guide rod is located in the hollow part of the support column, and the bottom end of the guide rod can contact the cam.

[0020] The beneficial effect of the basic scheme is that when cleaning the patient's wound, the cleaning liquid flows through the fan blades through the output pipe, and the fan blades can rotate under the impact of the liquid flowing through, thereby driving the rotating shaft to rotate accordingly, so that the cam rotates accordingly, and when the cam rotates, the cam can contact the bottom of the guide rod, and then the guide rod can be subjected to a certain jacking force under the action of the cam, thereby providing a certain shaking force for the support plate, thereby increasing the shaking of the accumulated water on the patient's skin surface, so that the flushing liquid on the patient's skin can flow down smoothly, and the slight shaking plus the flushing force at the flushing nozzle can increase the impact force of impurities on the patient's wound, so that some stubborn impurities can also be washed away, reducing the impact of insufficient flushing on the patient's wound;

[0021] At the same time, the rotation size of the fan blades changes with the pressure of the cleaning fluid output. When the fan blades are subjected to high cleaning fluid pressure, the fan blades rotate faster and more cleaning fluid is output at the same time. The faster the fan blades rotate, the more frequently the guide rods are pushed by the cam, and the more cleaning fluid and impurities can be cleaned. Anyway, the slower the fan blades rotate, the less water accumulates in the patient's wound, and there is no need to shake the cleaning fluid more frequently to process it. In this way, the changes in the water pressure of different cleaning fluids driven by the pump assembly can be achieved to achieve a suitable small-amplitude vibration of the patient's limbs, realizing the effect of resource reuse and full cleaning.

[0022] Furthermore, a plurality of second springs are provided on both sides of the guide rod, the second springs are fixedly connected to the inner wall of the support column, and elastic blocks are fixedly connected to the connection between the bottom of the support plate and the support column.

[0023] The beneficial effect of the basic scheme is that when the guide rod is pushed by the cam, the guide rod can produce a corresponding swinging motion amplitude driven by the second spring, thereby increasing the irrigation liquid on the wound surface to be guided out under the action of inclination, and at the same time the second spring can provide a certain support force for the guide rod and increase the stability of the guide rod.

[0024] Furthermore, a feed port is provided on one side of the liquid storage tank, a closing plug is provided on the feed port, a motor is provided at the bottom of the liquid storage tank, an output shaft of the motor passes through the bottom of the liquid storage tank and extends into the liquid storage tank, the motor output shaft is coaxially fixedly connected to a stirring shaft, and a number of stirring rods are fixedly connected to the stirring shaft.

[0025] The beneficial effect of the basic solution is: clean water and cleaning liquid are injected into the storage box through the feed port, and the motor is started at the same time. The stirring shaft can rotate under the drive of the motor, and the stirring rod can fully stir the cleaning liquid in the storage tank, thereby reducing the problem of insufficient mixing of the cleaning liquid.

[0026] Furthermore, a support seat is fixedly connected to the bottom of the liquid storage tank, and the support seat ring is arranged on the upper side wall of the motor.

[0027] The beneficial effect of the basic solution is that the support seat can increase the stability of the device.

[0028] Furthermore, a fixing groove for fixing the flushing nozzle is fixedly connected to the top of the liquid storage tank, and the inner wall of the fixing groove is provided with anti-slip grooves.

[0029] The beneficial effect of the basic solution is that when no cleaning operation is performed, the flushing nozzle can be placed in the fixed groove and fixed, thereby reducing the problem of inconvenient placement of the flushing nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The flushing nozzle 10 includes a fixed body, a flushing channel is provided in the fixed body, the flushing channel is communicated with the output pipe 3, a baffle 24 and an auxiliary ring are provided at one end of the fixed body away from the output pipe 3, a through hole 25 corresponding to the position of the flushing channel is provided on the baffle 24, a plurality of first springs 23 are fixedly connected to the baffle 24 along its circumference, and the other end of the first spring 23 is fixedly connected to the inner side of the auxiliary ring;

[0040] The auxiliary ring is composed of a plurality of moving rods 19 forming a square rectangular ring. The moving rods 19 are each provided with a sliding block 21 at one end close to each other. The moving rods 19 cross and pass through the sliding block 21 and extend outside the sliding block 21. The bottom of the sliding block 21 is provided with a first protrusion. The fixed body is provided with a plurality of first sliding grooves 22 corresponding to the position of the first protrusion on one side close to the sliding block 21. The sliding block 21 and the fixed body are slidably matched through the first protrusion and the first sliding groove 22. One end of one of the sliding blocks 21 away from the baffle 24 is fixedly connected with a push rod 26, and the push rod 26 passes through the fixed body and extends outside the fixed body.

[0041] A second protrusion is provided at the bottom of the center of the moving rod 19 , and a second slide groove 20 corresponding to the position of the second protrusion is provided on the fixed body. The moving rod 19 and the fixed body are slidably matched through the second protrusion and the second slide groove 20 .

[0042] The specific implementation process is as follows: first, clean water and cleaning liquid are injected into the storage box through the feed port 12, and the motor 16 is started at the same time, and the stirring rod 13 can fully stir the cleaning liquid in the storage tank 1, thereby reducing the problem of insufficient mixing of the cleaning liquid;

[0043] Then, the wound of the patient is cleaned. The patient may have multiple wounds. When cleaning, the wound of the patient is first placed on the wound support part. The medical staff holds the flushing nozzle 10 and starts the pump assembly 2 at the same time. The flushing nozzle 10 is aimed at the wound of the patient, and the wound of the patient can be cleaned. When the positions of the two wounds of the patient are close, the flushing nozzle 10 is generally directly moved to the wound;

[0044] When the medical staff moves the flushing nozzle 10 to the next wound, because the baffle 24 can initially connect the through hole 25 on the baffle 24 with the flushing channel under the support and balance of the first springs 23, when the flushing nozzle 10 is moved, under the action of inertia, part of the first springs 23 will contract and part of the first springs 23 will extend, and then at this moment the through hole 25 of the baffle 24 will be offset from the position of the flushing channel, and then the flushing liquid cannot be output at this time, thereby temporarily closing the flushing nozzle 10, and when the nozzle moves to the next wound, because the flushing nozzle 10 does not perform a corresponding movement at this time, and then the inertia caused by the movement of the first spring 23 disappears, and thus the first spring 23 is reset, thereby realizing the realignment and connection of the through hole 25 on the baffle 24 with the flushing channel, thereby realizing the flushing of the next wound of the patient;

[0045] And by pressing the push rod 26 by hand, the sliding block 21 can slide under the action of the push block, because the moving rods 19 all cross and pass through the sliding block 21 and extend outside the sliding block 21, and then the moving rod 19 can perform corresponding sliding movement under the movement of the sliding block 21, wherein the push rod 26 is pressed, the sliding block 21 moves toward the side of the baffle 24, and the moving rod 19 also moves toward the side of the baffle 24, because the sliding block 21 and the moving rod 19 form a square as a whole, the other moving rods 19 and the sliding block 21 can be moved as a whole under the drive of the push rod 26, when the moving rods 19 all move toward the side of the baffle 24, the elastic path of the first spring 23 can be reduced, otherwise the elastic path of the first spring 23 can be increased, thereby realizing that the through hole 25 at the baffle 24 can flexibly change the connection size with the flushing channel, thereby adjusting the water pressure of the flushing liquid.

[0046] Example 2

[0047] The difference from the above embodiment is that a cavity is provided at one end of the fixed body away from the baffle 24, a pulse generator is provided in the cavity, the pulse generator is connected to an actuator, the actuator is located in the cavity, and the pulse generator is electrically connected to a power supply.

[0048] The specific implementation process is as follows: turn on the pulse generator, and then the actuator executes the corresponding pulse model emitted by the pulse generator, so that the flushing nozzle 10 can generate a corresponding pulse movement, and the first spring 23 can generate a corresponding telescopic movement under the influence of the movement again, so that the baffle 24 moves to a certain amplitude, so that the through hole 25 and the flushing channel can achieve position changes, and then the flushing liquid can be in a form of sometimes large and sometimes small to flush the patient's wound, thereby reducing the problem of high-pressure flushing of the patient's wound and causing discomfort to the patient.

[0049] Example 3

[0050] The difference from the above embodiment is that the wound support portion includes a support plate 6 and a hollow support column 4 arranged from top to bottom, a fan blade 8 assembly is arranged in the hollow portion of the support column 4, and the fan blade 8 assembly includes a rotating shaft 18 and a plurality of fan blades 8 fixedly connected to the rotating shaft 18, and both ends of the rotating shaft 18 are rotatably connected to the inner wall of the support column 4;

[0051] The output pipe 3 is partially fixedly connected to the top of the liquid storage tank 1, and the output pipe 3 passes through the hollow part of the support column 4 and extends out of the hollow part of the support column 4, and the fan blade 8 is located in the output pipe 3, one end of the rotating shaft 18 passes through one side of the output pipe 3 and extends into the hollow part of the support column 4, a sealing ring 17 is provided at the connection between the rotating shaft 18 and the output pipe 3, and one end of the rotating shaft 18 located in the support column 4 is fixedly connected to the cam 9;

[0052] A guide rod 7 is fixedly connected to the bottom of the support plate 6, and the guide rod 7 is located in the hollow part of the support column 4, and the bottom end of the guide rod 7 can contact the cam 9; a plurality of second springs 5 ​​are provided on both sides of the guide rod 7, and the second springs 5 ​​are fixedly connected to the inner wall of the support column 4, and an elastic block is fixedly connected to the connection between the bottom of the support plate 6 and the support column 4.

[0053] The specific implementation process is as follows: when cleaning the wound of the patient, the cleaning liquid flows through the fan blade 8 through the output pipe 3, and the fan blade 8 can rotate under the impact of the liquid flowing through, thereby driving the rotating shaft 18 to rotate accordingly, so that the cam 9 rotates accordingly, and the cam 9 can contact the bottom of the guide rod 7, and then the guide rod 7 can be subjected to a certain jacking force under the action of the cam 9, thereby providing a certain shaking force for the support plate 6, thereby increasing the shaking of the accumulated water on the patient's skin surface, so that the flushing liquid on the patient's skin can flow down smoothly;

[0054] The rotation size of the fan blade 8 changes with the pressure of the cleaning liquid output. When the fan blade 8 is subjected to a large pressure of the cleaning liquid, the fan blade 8 rotates faster and more cleaning liquid is output at the same time. The faster the fan blade 8 rotates, the more frequently the guide rod 7 is pushed by the cam 9, and the more it can clean up the cleaning liquid and impurities. Anyway, the slower the fan blade 8 rotates, the less water accumulates in the patient's wound and there is no need to shake the cleaning liquid more frequently to process it.
